Wow, thank you! I'm very happy to hear how much you enjoyed it~. And yeah, a lot of lewd stuff seems to neglect making things fun for the ladies as well, so I do try to avoid that in my writing.
Hmm, an ingame completion log would be rather tough I think, just cause I do tend to go back and add things to finished areas, which would throw things off. For original Lust Doll, you can try the wiki (http://wiki.smutosaur.us/LustDoll/) to see if there's anything you've missed. For Lust Doll Plus, I do have a full scenes guide that I'm keeping updated, but it's only available to backers I'm afraid (Sorry!) Usually though, I'll block off areas that can't be completed yet, and looking at the change log that comes with the readme file will often tell you what's been added to each version. Plus you can always ask here XD.
